It isn't this worse at all :-)

First, your syntax is not correct.
Second, you can change the 'IN' Clause with several 'OR' clauses.
The result would look like this:

create table kev_test ( my_tag char) constraint tester check (my_tag =
'A' OR my_tag='B' OR my_tag = 'C');

If somebody has a solution for the 'IN' construction.... mail it!

So long,
Holger
